通常来说,为了避免快速排序退化为冒泡排序,以及递归栈过深的问题,我们一般依据“三者取中”的法则来选取基准元素,“三者”即序列首元素、序列尾元素、序列中间元素,在三者中取中值作为本趟快速排序的基准元素。 原文链接:图解快排--快速排序算法(quick sort) ...
Quick Sort Algorithm with C++ Example: In this tutorial, we will learn about the quick sort algorithm and its implementation using the C++ program. By Amit Shukla Last updated : August 06, 2023 Quick sort is an efficient, general-purpose sorting algorithm. It was developed by British ...
Quicksort算法属于divide and conquer算法,核心思想是取array中的一个元素作为pivot,然后把array除了pivot的其他元素与这个pivot进行比较,比pivot小的元素放在pivot左边,比pivot大的元素放在pivot的右边,我们就得到了两个subarray(左边和右边),然后再对新的subarray进行同样的操作,直到得到新array中只有一个元素。 二、qui...
